Nozzles were spaced 15 inches apart along the 15 foot boom length extending from the center of the drive-line off to the right side of the sprayer; 11 nozzles were used on the boom. Different pressures, rpm, and speeds were used for the application so that the pressure range at the sprayer varied between 15-20 psi. TeeJet 8001 nozzles were used for the SWF2 level. TurboTeeJet 11002 nozzles were used for the SWF3. TurboTeeJet 11003 nozzles were used for the SWF4, SWF5, levels. TurboTeeJet 11005 nozzles were used for the SWF7, SWF7 and SWF8 levels.
